recovery from an ore containing 3 g/t Au and high levels of arsenic. Treatment of the sulphide ore involves gravity separation, flotation, and cyanide leaching. A gravity concentrate is recovered within the grinding circuit before the ore is subjected to froth flotation. The concentrate from the flotation circuit is then
Three-stage cleaner flotation released grades of 25% Cu and 5–10 g/t Au at recoveries of 87% and 70% respectively for the chalcopyrite-pyrite ore. The chalcocite ore produced higher copper grades in the range of 60% Cu with 5–10 g/t Au, with similar recoveries to those of the chalcopyrite–pyrite ore.
the flotation-smelting-matte refining process for treatment of nickel sulfide ores is presented in Figure 1. There is great deal of variation in the standard flow sheet with respect to flotation practice (i.e. mineralogy, liberation size, reagents, etc.) and converter matte refining, however concentrate smelting is
Moreover, the flotation kinetic model of copper slag was established and the results showed that the movement of copper slag in the flotation process conforms to the first-order kinetics.
